BPH remains one of the most common diseases that the urologist has to manage. The last decade brought numerous new techniques, aiming to improve the minimally invasive approach to BPH, but, for the moment, none had changed the place of TURP as the gold standard treatment for medium sized prostates. Based on a large personal experience, the authors present a study in which TURP is used for prostates over 80 ml, the cutoff point set by the guidelines of the European Association of Urology. The rationale for this study is that many situations require minimally invasive treatment, based on the express request of the patient, other conditions that makes open surgery very difficult or impossible, or the need for a quick discharge in an overcrowded service. The aim of the study was to prove that TURP is safe and effective even in larger prostates. The technique used is basically the classic one, with minor tactical alterations in some cases. Some cases required a two-stage approach, but offered good functional results after the first stage. The results proved that, with a good technique, a skilled urologist might achieve the same results by using TURP or open surgery for large sized prostates.
